Birdy... You spend $100 on filters a year for your 46gal?!? Should I figure double that for my 90? What kind of unit do you have and roughly how many gallons of RO(DI) water do you get before the filters need changing? Thanks.

I just recently bought a 90 gallon AGA RR tank. I found out that just about every LFS around me had a different price. It turns out that their price from All Glass was mostly dependent on how many tanks they sell a year. For my 90 I did some shopping around. I ended up driving to a LFS about...

My local store has RO water for 29 cents a gallon. First, is this considered a good price? Second, this is their filtration method - is this okay? 1) Sediment filter 2) Activated Carbon filter 3) Reverse Osmosis (membrane) 4) Ultraviolet Light Just trying to decide on buying the water or...

Thanks for your input Jim. Each corner except for the overflow corner has 3 2X4's. Thats 9, plus 2 at the overflow corner. Then there are 4 in the middle. From what I hear the majority of the weight in a glass tank is pushed out toward the 4 corners - with less than you think being directed...

I'll be putting on plywood all the way around the stand - would this be enough 'cross-bracing'? This is for a 90gal. Total expected weight is 1700 lb. (as estimated from here ) The dimensions of my stand are 48.75 x 18.75 x 33.

Here's a look at what I'm thinking of doing. Pretty similar to many that I've seen shown on this board. I've just changed the upper left corner to make room for the AGA overflow on my 90. Does anyone think this would not be sturdy/strong enough?? Thanks.

Hey Jim... Would love to see some pictures if you get the chance...:D Thanks.

Cool.. Thanks for the info Rane!!

Beth... Do you know if I put the whole RO/DI with tank under my sink if I can then run a long (~10 feet) hose from the DI to my basement collection container. The length of travel would be all heading down hill. I'm thinking that the length shouldn't matter as long as gravity is working on...

I did some searching and found this picture. Credit for the idea is here

Ugh, just when you think you got your plan nailed - you get Banged! ;) ;) Thanks a bunch Bang Guy - you make some very good points. It will be easy to alter this to divert water from the overflow line like you suggested. Much better, I agree. -- Man, this board is great!

Thanks for the comments Krux! I like the idea of the bulkhead/elbow to prevent noise and bubbles!!. And the strainer would help prevent caulerpa clippings from accidentally getting into the main pump ;) ;)

I'm trying to solve this same issue... I'd love to see some more ideas if anyone out there has some! Bump. :)

Hey Tucker... Do you still have those AutoCAD drawings of your stand?? I'd much appreciate getting a copy :D Thanks a bunch!

Prater... yeah, I guess that makes sense. The bubbles need to rise to the top to break. Having the water travel back down probably doesn't accomplish much. Although I do have some egg crate there to put carbon on - where would be a good place to use carbon if not there?

Hey Guys... just one more question. I know, I know.. I'm overanalyzing this design :D With my 3 baffel (divider) setup... is there a difference between having the water go "under-over-under" like I have it vs. how some set them up to go "over-under-over" ??? Tanks! :)

Great... thanks for the help.... Here's an updated drawing:

Designing this thing in 2D I forgot that I've got depth to work with too! I see what you mean about the first divider. I'm going to take it out and move the skimmer over. I can always put in a small container of some sort for the overflow line to run into. Now my first chamber is bigger...

and another question.... Is 1.5" spacing for the baffles too small... I want a lot of flow and I'm wondering if this would restrict it at all???

Juggernaut... Yes, thanks for the ideas. BTW I used Viso to do this sketch. Do you think it would be worth taking another 1.5" away from the fuge to add in another baffel?? My other thought is moving the skimmer out of the sump in order to make the refug portion larger. I haven't decided on a...
